// Package unix contains an interface to the low-level operating system
|
|
// primitives. OS details vary depending on the underlying system, and
|
|
// by default, godoc will display OS-specific documentation for the current
|
|
// system. If you want godoc to display OS documentation for another
|
|
// system, set $GOOS and $GOARCH to the desired system. For example, if
|
|
// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
|
|
// to freebsd and $GOARCH to arm.
|
|
// The primary use of this package is inside other packages that provide a more
|
|
// portable interface to the system, such as "os", "time" and "net". Use
|
|
// those packages rather than this one if you can.

// For details of the functions and data types in this package consult

// err represents an operating system error describing the failure and

// holds a value of type syscall.Errno.
